Patent GB-2111689-A (GB)
Title: Touch sensitive switch
Inventor: HILSUM CYRIL
IPC: H03K17/96
Filed: 1982-11-12
Abstract: The switch comprises a liquid crystal cell (1, 20) and means for measuring capacitive changes when the cell is deformed by touch. The cell (1) comprises a layer (8) of a liquid crystal material between slides (2, 3) bearing electrodes (5, 6). Capacitive changes are detected for example by a comparator (Fig. 4) or by a bridge circuit which includes one or more cells. Touching one cell unbalances the bridge. The area of cell that is touched may be coincident with (Fig. 1) or separate from a display area. For some types of cell extra sensitivity is achieved by maintaining a voltage across the cell between a critical and saturation value. <IMAGE>

The inlet valve 8 of the engine is positioned towards an end of the upper horizontal wall 5a so that a valve disk 8a of the inlet valve 8 is orientated in parallel with the upper horizontal wall 5a. The inlet passage 10 is substantially tangentially orientated at with respect to the cylinder 1 and extends above the vertical wall 5b to cause charge swirl about the cylinder axis. <IMAGE>

Title: Communications systems
Inventor: PEILE ROBERT EDWARD
IPC: H04L25/49
Filed: 1983-09-09
Abstract: Data from a primary data source S1 is encoded using a redundant code and further data from a source S2 is selectively introduced when channel interference conditions permit by adding modulo 2 in an adder 10 to some of the bits or symbols of the output code word derived from the encoded data from source S1, or by substitution (Fig. 2). At the receiver decoder (14), the data S1 is recovered and an error string is generated each bit of which indicates the presence or absence of an error in each bit or symbol of the received data. The bits of the error string corresponding to those bits or symbols which were modified to introduce the further data from the source S2 correspond to the recovered data S<1>2. The combined data from sources S1 and S2 may be subject to encoding (4) and decoding (8) at either end of the channel (6). <IMAGE>

Patent GB-2159901-A (GB)
Title: Pipe joints
Inventor: PRICE JACK ROLAND CHARLES
IPC: F16L21/00
Filed: 1984-05-17
Abstract: A water tight connection is made between a lead pipe 9 and a water pipe of brass, copper or stainless steel by inserting an inner support liner 4 having a larger-diameter portion 7 into pipe 9 and clamping a two-section brass block 3 around the end of pipe 9 by virtue of bolts 5. The larger diameter portion 7 of support liner 4 provides a fixture for the connecting fitting of the other pipe. The use of solders or heated metal with consequent requirement for shutting off the water supply is therefore avoided.

Patent GB-2148327-A (GB)
Title: Making liquid steel
Inventor: EDSTROM JOHN OLOF
IPC: C21B13/00
Filed: 1984-09-26
Abstract: When manufacturing liquid steel from highly concentrated iron-ore concentrate, especially iron-ore concentrate containing phosphorous, a charge material is produced by sintering a mixture comprising substantially the afore-mentioned concentrate and basic slag-forming agents including CaO and MgO. The composition of the mixture is adjusted so that the charge material contains calcium oxide in an amount corresponding to at least 35% of the total weight of the non-iron oxide content of the charge material, and calcium oxide and magnesium oxide in a total amount corresponding to at least 55% of the total weight of the non-iron oxide content of the charge material, and also exhibits a weight ratio of CaO: MgO of at least 1.3. The charge material is reduced in solid phase to form sponge iron having a degree of metallization of at least 80 %,whereafter the sponge iron, optionally together with another iron-bearing material, is smelted in a steel furnace under such conditions as to maintain in the slag formed during the smelting process an iron-oxide content of at least about 5% by weight, and the resultant liquid steel and slag are separated from one another.
Patent GB-2155647-A (GB)
Title: Controlled exposure
Inventor: SUZUKI AKIYOSHI
IPC: G03F7/20
Filed: 1985-01-24
Abstract: A wafer is exposed to an excimer laser beam, the amount of exposure being controlled by using a plurality of pulses of the same preset energy value alone (Figs. 5 and 6) or followed by one or more pulses of lower preset value (Figs. 7 and 8). In the latter case, the required pulse energy of the additional pulse(s) is calculated using photosensor 5b, integrator 6 and comparator 9. The invention substantially overcomes the problem of deviation of individual pulse output from a preset energy value. <IMAGE>

Title: Rotary scroll-type fluid machine
Inventor: HIRANO TAKAHISA
IPC: F01C17/06
Filed: 1985-02-21
Abstract: The machine has a stationary spiral element 600 nested with a movable spiral element 601 and, in use, the central portion of element 601 moves around a circle defined about the center of the element 600, and the portion distant from said central portion moves in reciprocating motion in either a rectilinear or an arcuate locus. In view of such complex movement of the element 601 it is necessary to maintain the desired cooperating relationship between the two nested elements 600,601. This is achieved by providing a limit element or elements, e.g. a link 651, balls (751, Fig. 16) or keys (Figs. 20 to 27) between the nested elements. <IMAGE>

Title: Improvement in the flavour of zinc supplements for oral use
Inventor: GODFREY JOHN CARL
IPC: A23L1/304
Filed: 1985-06-10
Abstract: Formulations of zinc compounds with select amino acids such as glycine (aminocetic acid) in a base material. The base material can be a sweetening agent such as a hard or soft candy base, a syrup, chewing gum, dentifrice, or the like. The advantage of such formulation is that the unpalatable and undesirable tastes and aftertastes of unformulated zinc compound and of zinc compounds mixed with a base material are markedly reduced and the products may be slowly dissolved in the mouth to achieve nutritional or therapeutic results. Processes for the satisfactory preparation of the formulations are set forth.

Title: Method of producing flexible hoses with one or more laterally attached branch hoses
Inventor: GIELER JOACHIM
IPC: B29C65/68
Filed: 1986-08-27
Abstract: Moulded hose branches, such as are required, for example, for the cooling system of motor vehicle engines, are produced in accordance with known methods by inserting an angular pipe moulded part (3) made of a metal or plastics material into the hose line, the hose ends (1, 2) being slipped over the pipe connections of the moulded part and vulcanised together therewith. According to the invention, the hose ends (1, 2) are additionally secured by elastomeric annular members (4, 5) formed from plastics material which shrinks when subjected to heat, the annular members (4, 5) being slipped over the hose ends in the manner of clamps and being vulcanised together therewith. The annular members simultaneously serve to apply the pressure required to produce the vulcanised connections. During use, the moulded hoses increase the strength of the branch and its sealing quality, even when subjected to intense variations in pressure. <IMAGE>
Patent GB-2197216-A (GB)
Title: Climbing toy
Inventor: CHEUNG KWOK LAM
IPC: A63H11/04
Filed: 1986-11-07
Abstract: A toy creature (C) has pathways (P) at the ends of a rigid pair of legs (10). Strings (1,2) pass through these pathways (P) and, when one string is pulled down more tautly than the other, the one string will be gripped in the respective pathway (P) and the legs (10) will pivot thereabout. The pathway (P) through which the other string passes is able to slide up that string, and the legs (10) may therefore be made to climb up the strings (1,2) by pulling down alternately on the strings. In order to simulate a creature such as an animal, a pair of arms (9), a head (7) and the legs (10) may be pivotally connected to a torso (5). If the arms (9) and legs (10) are provided with interengaging toothed racks (13,14), rotation of the legs (10) will cause the arms (9) to rotate in the opposite direction. This provides a more realistic approximation to a climbing creature. <IMAGE>
